Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 39 Issued at 2200Z on 08 Feb 2014

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C8 event observed at 08/1833Z from Region 1967 (S13W77). There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate with a slight chance for an X-class flare on day one (09 Feb) and expected to be low with a chance for M-class flares on day two (10 Feb) and likely to be low with a slight chance for an M-class flare on day three (11 Feb).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 476 km/s at 08/0819Z. Total IMF reached 14 nT at 08/0010Z. The maximum southward component of Bz reached -9 nT at 07/2201Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels on day one (09 Feb), quiet to unsettled levels on day two (10 Feb) and quiet levels on day three (11 Feb). Protons greater than 10 Mev have a slight chance of crossing threshold on days one and two (09 Feb, 10 Feb).
